Buscamos com essa pesquisa identificar caracter?sticas do design em interfaces de aplicativos para o contexto do jornalismo em dispositivos m?veis, visando orientar a editora??o visual e de conte?do, e o processo de cria??o e desenvolvimento das interfaces de apps, com a inten??o de garantir a qualidade da intera??o por toque, respeitando-se as limita??es do usu?rio, possibilidades que o dispositivo proporciona e requisitos do aplicativo. A pesquisa tem como objetivo o estudo da interface do aplicativo Brasil 247, que ? utilizado para veicula??o de not?cias utilizando os conceitos de usabilidade e ergonomia que viabilizam projetos coerentes entre seus aspectos de necessidade de imers?o (flow) e mobilidade, tratando principalmente quest?es de adapta??o, busca e leitura desse conte?do no uso do aplicativo, bem como esclarecer sobre os processos e t?cnicas necess?rios para a realiza??o desses ensaios de intera??o que buscam avaliar a usabilidade da interface. / The different characteristics and needs of mobile device users, the situations in which these devices are operated and the limitations and characteristics of these devices are all factors which influence usability and ergonomics; two elements highly required for achieving successful interaction between users and devices. This research aims to identify characteristics of interface design for apps in mobile device applications, focussing on design, visual publishing and content editing, and the actual process of creation of these interfaces, with a view to guarantee quality interaction through touch technology, in observance of service limitations, the opportunities offered by the devices and the application requirements. The study will examine the interface of the mobile device application titled ?Brasil 247? which provides news broadcasts using the concept of usability and ergonomics mainly in the field of adaptation, searching and browsing informative articles, as well as clarifying the processes and techniques necessary to carry out interaction tests which seek to evaluate the usability of interface.
